-.-1- lli--- illustrating the brakeopera'ting mechanism, the brakeshaving been restored' to initial or inoperative position, and theapparatus being at rest. showing the parts in process of being restoredto initial position. Fig. i3 isa view from the side opposite to thatseen 1n Fie.

11. Fig. le illustrates the means for locking the brakes in initialposition. Fig. l5 shows a means for preventing the Warper from be'- ingoperated until the brakes have been re- "stored to initial position.Fig. 16 illustrates Suitable means (not herein shown) may be employed toprevent the formation of an eccentric yarn mass on the beam. l) are thedrop Wires for detecting thread breakages, and F the usual slack-take-uproll res ,ing upon the sheet of Warp threads. As herein beforesuggested, the threads are kept taut at all times by the co-action ofthe cheese brakes and the beam brake and Without the assistance of theiall roll llhthe latter being retained in the Warper for the purpose ofpreventing slack in case of va sudden accidental decrease in the speedof the beam, ior the purpose of indicating to the operative when thebeam brake requires adjustment, and to prevent slack when the beam comesto rest after having been revolved slowly preparatory to going ontohigher speed.

'.W'hile the invention in its broadest aspect is applicable to theunvvinding ol" various forms of .yarn masses, it is herein illustra-tedas embodied in a machine for un- Winding yarn masses in the form olicylindrical cheeses .'z. Each cheese consists of yarn cross-Wound upon acheese tube la). ln the illustrative forni herein shown, the cheese tubeconsists of two cylindrical sheet-metal sections t1 and t2 rigidlysecured together, each of said sections having an annular' end Wall 253.ln each of the 4end Walls hais a central opening surrounded by aninturned flange et. A sleeve t5 extends centrally of and Within thesections 51 and 62 and surrounds the flanges In the Creel the cheesesare rotatably supported upon spindles l, four cheeses, in the presentembodiment being carried by each spindle. The cheese tubesare notmounted directly upon the sl'iindle, but are carried-by rollers 2 Whicharei'otatably supported upon the spindle. ln the construction hereinshown, each roller is formed of sheet metal `and comprises annularhearing anges 2a Fig. l2 is a ragniental vieWf nannies supporting thebearingfianges b* of .the

cheese tubes. By reason of such reduction 1n diameter the roller has agenerally crowning Aforni which prevents the cheese from 4movinglaterally .into contact with the ad3acent 'cheeses Whenrevolving in' thecreel.

The greatest diameter ofthe roller 2 is sutil l'cie'ntly less than thesmallest internal diameter of the cheese tube so-that the latter'may be'readily slipped on and ofthe roller :by the operative. a

The rollers are prevented from being displaced' endWise by means ofsleeves il Which.- arerotatably mounted uponthe spinv dle l between therollers. The ends of 4the rollers are' countersunk so as to overhang thesleeves 3, and sleeves are provided near their 'y ends with annularflanges which prevent yarn from getting between the ends of the rollers2 and sleeves 3. case some yarn should become Wound around one of thesleeves 3, the yarn may be readily'unwound therefrom, as the sleeve'will rotate freely as the yarn is Withdrawn.

To lubricate the spindles 1, a small quantity of oil n? is placed ineach roller 2 before theA roller is placed upon the spindle in theoperation of assembling the` parts. The quantity of oil is preferably sosmall that the level of the oil never touches the spindle Whether thespindle is `in horizontal or vertical position. When the spindle is inthe creel andthe rollers .2 are revolving, seme of the oil is carried uponto the outer surface of the 'flanges 2. When the spindle lib lissubsequently' placed in vertical position,

some of the oil onV said iianges flows onto the spindle.

In the construction herein illustrated, the spindles l are arranged ingroups of three, each group, being 'fixed to a base 4: (Figs. la and 8).Upon the end of each spindle is mounted a cap Spacer sleeves 3 areprovided to space the rollers from the cap andthe base. Each base l withits row of spindles l will hereinal*l er be termed a trident. Thetridents are adapted to be used at the Winder as a receptacle or asupport tor the cheeses When the latter are removed Jfrom the Winder.lhen in use at the Winder, the tridents rest upon the bases 4 with thespindles l in upright position. When in such 4position the cheese tubeson a given spindle rest upon one another. `When the tridents are in usein the creel, the spindles occupy a horizontal position, the cheesetubesv being out lof contact with each other.

The framework of the creel may be of any suitable character. As vhereinshown, it consists of tvvo upright frames 6' and 7 (Fig. 3) whichareadjacent each' other at vided with thread posed .of six bays, eachadapted to support` three tridents arranged one above the other. lThetridents are insertible and removable through the outer sides of theframes 6 and.

7. At'the'left-hand side of' each bay are sockets 8 (Figs. 3, 5 and 8),each intended to 4receive one end of the base 4f of a trident, At thefront end of each socket 8 is a projection 9 on which the operative maymomentarily rest the base of the trident while placing the trident inthe Creel-frame.-

At the right-hand side of the bay are sockets 10 (Figs. 1 and -5) toreceive the caps 5. For each socket 10 there is a guide iange 11 toassist the operative in setting the triflent in place. Each bay isprovided on its outer side with a gate l2 hinged at 13. (See Figs. 3, 8and 10.) The gate is held shut by means of a projection 14 (Fig. 10) onthe gate adapted to lie inl a recess 15 on a locking member 16 fixed tothe creelframe. Each gate is provided with guide rods 17 for guiding thethreads from the cheeses to thewarper.

The mounting of a pluralityof cheeses upon each spindle conduces to avery compact arrangement of the cheeses in the Creel,

-as will be apparent from Fig. 2.

The Winder operatives place the cheeses vupon the tridents in such amanner that when the tridents are set in' thecreel-frame the yarn shallunwind. from the upper portions of the cheeses. As the tridents may beset in the Creel-frame with either end up. the warner tender can placethe tridents without giving any attention to the matter of seeing thatthe yarn unwinds from the upper part of the cheeses. After placing thetridents inthe creelframe, the warper tender spaces the cheeses properlyupon the spindles, so that each cheese rests upon its roller 2. f

It will be seen that the creel comprising as. it does tridents each ofwhich is supplied' with twelve cheeses at the Winder, mavbe filled andemptied verygquicklv, and with a minimuprof handling of the cheeses.

To keep the'yarn from some of the lower c cheeses out of contact withthe next higher cheeses, certain of the guide rods 17 are pro- Referringnow to the cheese brakes: At any given stop each cheese coasts about thesame amount-as all the other cheeses, because the cheeses are allapproximately the same size, and because of the character of the brakingsurfaces. One of these surfacesis the surface of the yarn mass and theother guiding notches 18 is a polished metal plate. The rubbing of theyarn against the plate in stopping keeps the plate bright so that thesurface condi'- tion of the plate-remains very nearly constant. Asstated, the other braking surface is the yarn, and as a new surface 4isconstantly being resented to the brake (owing to the unwinding of theyarn) there is no change in the characteristics of this surface due towear, and other changes due to such causes as temperature and humidityaffect all o'f the cheeses-alike. l

l19 indicates the polished metal plate comprised in each cheese brake.The plate is .preferably curved so as to present a convex surface to theyarn mass and is arranged to bear against the middle of the periphery ofthe cheese in order that when the plate is pressed against the cheesethe latter shall not be tilted so as to bring its tube b into contactwith an adjacent' tube. l

vThe brake plates 19 are pivotally mounted upon rock shafts'20 which aresupported upon the inner side of the-creel-frame.

21 are individual torsion springsfor the brake plates, one end of eachspring'being secured'to the rock shaft andthe other end to the brakeplate. The springs 21 normally hold the brake plates 194 in contact withstop arms 22 fixed to the shafts 20, each arm having two lugs thatoverlie the adjacent brake plates. When the cheeses are to be braked,all of the shafts 20 are turned (by means to be later described) toswing the brake plates 19 against the cheeses. The rock shafts 20 areconnected together for simultaneous movement by means of crank arms 23and vertical connecting rods 2 4 (Figs. 3 and 8).-

In the upper portion of the creel is supported a horizontal rock shaft25 having arms 26 fixed upon its ends. These arms are connected to twoof the crank arms 23 by means of links 27 (Figs. 8 and 13). A tensionspring 28 anchored at one ,end4 to the creel framework and connected atitsr 28 is prevented from acting until the warper stop motion operatesby means to be now described. Fixed upon the rock shaft'25v is an arm30, on the upper end of which is pivoted a dog 31 (Fig. 14). 32 and 33are stops to limit the pivotal movementof the dogp The dog normally.bears against A A a stop 34 which is rotatably mounted in the.supporting framework. The rdog ,bears against the stop at a point belowthe axis of rotation of the stop and thus tends to turn the stop. Thestop is normally pre- "vented fromI turning 'by means 7of an arm' 35rigidly connected to the stop, one end of which arm bears against alatch 36 ,pivoted l helt. upon the-pulley 63, whereby the wheel 61 isset in motion. j

As the wheel 6i raises the arm 30, the cam 70 is withdrawn lfrom theprojection 71 on the arm 69. In order to prevent the spring 68 fromshifting the belt 65 to the loose pulley 64 until the wheel 61 hascompleted its work of raising the arm 30, I provide a lock for the beltshifter, which lckconsists of a latch 72 (Fig. 12|) which is pivoted at73 to the-supportmg framework, said latch having a shoulder arranged' toengage an arm 74 that is rigid with the shifter fork 66 and the arm 69.When the shifterfork 66 is moved to place the belt upon the tightpulley, the shoulder on the latch 7 2 drops behind the. arm 74 and thuslocks the belt shifter. The means for disengaging the latch 72 from thearm 74 comprises two dianietrieally opposite cams 75 on the wheel 61(see Fig. 12). After one of the roller studs 62 has raised the arm 30,one of the cams 75 comes into engagement with the projection 76 on thelatch 7 2 and lifts said latch clear of the arm 74, whereupon the spring68 shifts the belt' to the loose pulley. I' To prevent the wheel 61 fromrevolving beyond its proper initial position through momentum after thebelt 65 has been-shifted to the loose pulley, I provide a brake com-.prising a brake shoe 77 carried by an arm 78, said arm being piveted onthe airis of the wheel 61. The brake shoe 77 is arranged to engage theperiphery of the tight pulley 63. l

The braling pressure. is furnished by a spring 7 9 which acts upon anarm 8O that is rigid with the arm 78. When the drive belt isbeingshifted tothe tight pulley 63,

the brake shoe 77 lis removed from said pulley by means ofl a projection81 on lthe vshifter fork,..said projection engaging and moving the arm80. When the shifter fork places the belt upon .the loose pulley, the

^ .projection 81 is removed vfrom the arm 80,

whereupon the spring 79 presses the brake shoe 77 against the pulley 63and stops the rotation of the Wheel 61. After the warper stop motion hasoperated to stop the warper, the operative finds the thread-end on thevbeam and pieces up the thread. To facilitate the nding of the'end on thebeam, the operative may set the beam in slow rotation by depressing thetreadle T part way. After pieeing up the thread, the operative depressesthe treadle part way to start the beam slowly and then depresses thetreadle fully to throw in the high speed. To prevent any depression ofthe treadle until the operation of restoring the brake mechanism to itsnormal position hasbeen completed, I.l

provide a locking member 82 (Fig. 13), said locking member beingpivotally supportedrat 83 and being arranged to dropv .by gravity intoalinement with the bar 40 and thereby prevent movement of said bar andhence of the treadle T. Rigid with the locking member 82 is an arm 84which eX- tends into contact with the arm 74. When the belt shifter 66places the belt 65 0nthe tight pulley 63, the locking member .82 swingsby gravity into locking position. When the belt shifter moves the drivebelt to the loose pulley 64, the arm 74 operating the driving power andallowed to come to rest by taking the foot off the treadle. Vhen thebeam is thus stopped, the brakes are vnet automatically applied, as themovement of the bar 40 (Fig. 13) in setting the beam in slow rotationdoes Vnot cause the shoulder 42 to drop into the horizontal plane of thelug 43.

If desired, the creel may be provided with means for supporting a numberof extra cheeses, the yarn from which may'be substituted for the yarnfrom any of the other cheeses. Herein I have shown on .each 'reel framea stand 85 (Fig. 2), each stand having two spindles 86 which aregenerallysimilar to the spindles of the tridents. For each of the extracheeses there is a brake 19, the brakes on each stand being operatedfrom, the adjacent shaft 2O through a contherefore such extra strandsmay run to any space in the comb on the warper.

As hereinbefore stated, each cheese coasts about the same amount as allthe other cheeses at any given stop, the differences in coasting'beindue to slight differences in the size of the c eeses, as well as in thespring pressure of the brakes and in the friction in the bearings of thevarious shafts 20. On account of these varying factors it is impossible,with high winding speeds, to make the cheese brakes and the beam brakeeffective at the same-instant. p If it were attempted to make the cheesebrakes and the beam brake simultaneously effective', the threads of manyof the cheeses would be so slack as to cause trouble. beam brakesomewhat lessl effective in preventing coasting than the cheese brakes',thereby causing the .threads as a. rule to be I, therefore, make thebrake-controlling lever, thread-controlled means :t'or holding saidlever in brake-released position, said lever tending?,` to move intobrake-applied position,.means for moving said lever into brake-releasedposition, a starting and stopping device controlling said lever-movingmeans, and means connected to move with the lever for actuating te thestarting and stoppingf device.
